Wednesday’s Campaign Round-Up, 12.2.15

* In the new national Quinnipiac poll, Hillary Clinton now has a 30-point lead over Bernie Sanders, 60% to 30%. A month ago, Clinton’s advantage was a more modest 18 points.

* The same poll shows Clinton and Sanders leading each of the top Republican presidential contenders in hypothetical general-election match-ups.

* Jeb Bush’s new TV ad in New Hampshire highlights four Medal of Honor recipients. What those four military veterans have to do with Jeb Bush isn’t altogether clear.

* At a press conference yesterday in Paris, President Obama said he’s “anticipating” a Democratic successor. “I’m confident in the wisdom of the American people on that front,” he added.

* The far-right Club for Growth launched a new attack ad this week against Donald Trump. It focuses on, of all things, eminent domain.

* Speaking of anti-Trump ads, as Rachel noted on the show last night, John Kasich’s super PAC released an effective new spot this week, noting Trump’s mockery of a disabled journalist.

* In Florida’s Democratic U.S. Senate primary, Alan Grayson’s campaign appears to be running into some trouble: his campaign manager, deputy campaign manager, and senior adviser are each leaving their posts.

* And over the holiday weekend, the Denver Post published an interesting piece on the scope of the campaign investments made by “the conservative political network connected to the billionaire Koch brothers” in Colorado last year.
